The following shortcuts will work in almost any office application environment; I am especially pleased to use them when I browse the web.
CTRL + O (CTRL + L)
This will open the location field. In Internet Explorer you can use this to type in a web address.
CTRL + N
This will open a new application window, either an empty window or a clone.
In Internet Explorer the new window will show the same URL. So it is useful if you want to maintain the old browser window, and not having to leave the keyboard to open another browser window.
CTRL + TAB
Use this short cut to move between tab panes, use CTRL + SHIFT + TAB to move in reverse order.
